react-native-keyboard-aware-scroll-view

A ScrollView component that handles keyboard appearance and automatically scrolls to focused TextInput.

Supported versions

v0.2.0 requires RN>=0.32.0.
v0.1.2 requires RN>=0.27.2 but you should use 0.2.0 in order to make it work with multiple scroll views.
v0.0.7 requires react-native>=0.25.0.
Use v0.0.6 for older RN versions.

Installation

Installation can be done through npm:

npm i react-native-keyboard-aware-scroll-view --save

Usage

You can use the KeyboardAwareScrollView or the KeyboardAwareListView components. Both accept ScrollView and ListView default props and implements a custom KeyboardAwareMixin to handle keyboard appearance. The mixin is also available if you want to use it in any other component.

Import react-native-keyboard-aware-scroll-view and wrap your content inside it:

import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'

<KeyboardAwareScrollView>
  <View>
    <TextInput />
  </View>
</KeyboardAwareScrollView>

Auto-scroll in `TextInput` fields

As of v0.1.0, the component auto scrolls to the focused TextInput 😎. For versions v0.0.7 and older you can do the following.

Programatically scroll to any `TextInput`

In order to scroll to any TextInput field, you can use the built-in method scrollToFocusedInput. Example:

_scrollToInput (reactNode: any) {
  // Add a 'scroll' ref to your ScrollView
  this.refs.scroll.scrollToFocusedInput(reactNode)
}

<KeyboardAwareScrollView ref='scroll'>
  <View>
    <TextInput onFocus={(event: Event) => {
      // `bind` the function if you're using ES6 classes
      this._scrollToInput(ReactNative.findNodeHandle(event.target))
    }/>
  </View>
</KeyboardAwareScrollView>

Programatically scroll to any position

There's another built-in function that lets you programatically scroll to any position of the scroll view:

this.refs.scroll.scrollToPosition(0, 0, true)

Register to keyboard events

You can register to ScrollViewResponder events onKeyboardWillShow and onKeyboardWillHide:

<KeyboardAwareScrollView
  onKeyboardWillShow={(frames: Object) => {
    console.log('Keyboard event', frames)
  }}>
  <View>
    <TextInput />
  </View>
</KeyboardAwareScrollView>
